Phoenix Gold ZXM400.4ISO – Plug & Play ISO mini-amplifier
The Phoenix Gold ZXM400.4ISO is an ultra-compact 4-channel Class-D ISO mini-amplifier, specifically developed for easy and quick OEM upgrading of a car's original sound system. The amplifier is designed for true plug & play installation and is compatible with Phoenix Gold's complete ecosystem of plug & play cables, making it possible to upgrade more than 2,000 vehicles – completely without cutting, coding, or modifying the car's original wiring harness.
The ZXM400.4ISO is the ideal solution for users who want significantly better sound than the factory system, but without the need for DSP or complex setup. Despite its compact size, the amplifier delivers clean, efficient, and stable Class-D power, suitable for both OEM speakers and aftermarket systems.
The ISO-based design ensures simple and secure integration, while features such as Auto Start on high-level input, OEM Impedance Simulation (OIS), and fully adjustable filters ensure trouble-free operation – even in modern vehicles with sensitive factory radios.
